3/8" Hypercube Parts

These are the parts needed to make use of 3/8" rod or tubing that is easy to obtain here in the US. The bearing holder has in integrated IGUS type bushing that when printed in PETG filament has a very slick surface similar to the Drylin material. The parts were tested on 3/8" aluminum rod obtained from Lowes and I also include a bearing holder that is slightly over sized from that in case you get rod/tube that is slightly larger. The oversized bearing holder has ovrsz in the filename.
